Observed Aug 3, 2026, 01:14 UTC (5d ago). Every field below was attested with an Ed25519 signature at scan time.

This reading of l4d.com was taken 5d ago

l4d.com is on the survey sweep, which works its way across the whole catalog rather than returning to one name on a schedule. Putting l4d.com under watch moves it to the fast lane, where DomainDrift re-checks it about every 5 minutes and signs each reading, so a change becomes a dated event within minutes instead of waiting for the sweep to come round.

Watch l4d.com Watching a domain needs a DRM3 account. The reading above stays free and public either way.
